How wxWidgets cmake find in window - c++

Question

I can't find wxWidget on window. The error is:
CMake Error at E:/Program Files/JetBrains/CLion 2020.2.1/bin/cmake/win/share/cmake-3.17/Modules/FindPackageHandleStandardArgs.cmake:164 (message):
Could NOT find wxWidgets (missing: wxWidgets_LIBRARIES
wxWidgets_INCLUDE_DIRS)`
My Env:
win10
cmake 3.17
wxWidgets 3.1.4
I use cmake to build and install the wxWidgets
mkdir build
cd build
cmake .. -config Release
cmake --build .
cmake --install .
Which install wxWidgets in D:/Program Files(x86)/wxWidgets.
The I set the env variable wxWidgets_ROOT_DIR to D:\Program Files (x86), because that's a code snnipt in cmake's script FindWxWidgets.cmake.
find_path(wxWidgets_ROOT_DIR
NAMES include/wx/wx.h

)
I think I have config right the wxWidgets_ROOT_DIR. Because I message the varialbe message(wxWidgets_ROOT_DIR " " ${wxWidgets_ROOT_DIR}) and It show the right value:
D:/Program Files(x86)/wxWidgets
The I use find_libarray(wxWidgets Required) in my project to find wxWidgets, and it shows the above error.
My question is:
How to fix it.
Or what find_package(xxx) do on window?
Update:
I finally find it's clion issue that use his cmake not the stand cmake. I use the stand cmake with vscode. And they works fine.

I also had problems with wxWidgets installation on Windows and CLion, I' ve followed these steps:
Download MinGW(32) and set as the default compiler for CLion (I had problems with other compilers)
Download the windows installer of wxWidgets from the official site (https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.4/wxMSW-3.1.4-Setup.exe)
The installer will download all the files of the library in "C:\wxWidgets-3.1.4" and will also create the environment variable WXWIN that will contain the path of the folder "C:\wxWidgets-3.1.4"
Compile the library following this tutorial for MinGW https://wiki.wxwidgets.org/Compiling_wxWidgets_with_MinGW (make a coffee, it will take a while)
The compiler will but object files in "C:\wxWidgets-3.1.4\lib\gcc_dll", in "C:\wxWidgets-3.1.4\build\msw\gcc_mswudll" and probably in other places based on the instruction files in the "C:\wxWidgets-3.1.3\build" folder
After the compilation you need to add "C:/wxWidgets-3.1.4/lib/gcc_dll" in the environment variable PATH of the OS
After a restart write this code in the CMakeLists of your project:
cmake_minimum_required(VERSION 3.17)
project(your project name)
set(CMAKE_CXX_STANDARD 20)
SET(wxWidgets_USE_LIBS)
#for using RichTextCtrl
FIND_PACKAGE(wxWidgets REQUIRED richtext aui adv html core xml net base)
IF(wxWidgets_FOUND)
INCLUDE("${wxWidgets_USE_FILE}")
add_executable(your list of executables)
TARGET_LINK_LIBRARIES(note ${wxWidgets_LIBRARIES})
ELSE(wxWidgets_FOUND)
#for convenience. When we cannot continue,inform the user
MESSAGE("wxWidgets not found!")
ENDIF(wxWidgets_FOUND)
And now wxWidgets should work

I was able to build the samples using CLion and CMake on Mac OS, but much of what I learned should be similar, given CLion's cross-platform nature. The directions are very long, so here is a link:
